Abstract: A noise reducing system for video signal, comprises a vertical pre-emphasis circuit (13) supplied with an input video signal which is to be transmitted, for pre-emphasizing the input video signal and transmitting a pre-emphasized video signal to a transmitting system, and a vertical de-emphasis circuit (19) supplied with a pre-emphasized video signal which is pre-emphasized by the vertical pre-emphasis circuit and is transmitted through the transmitting system (14-18), for de-emphasizingthe pre-emphasized video signal. The vertical pre-emphasis circuit has a non-linear pre-emphasis characteristic for relatively emphasizing a high-frequency component of the input video signal in a vertical spatial frequency of a picture compared to a low-frequency component of the input video signal, with the degree of emphasis being reduced as the level of the input video signal increases. The vertical de-emphasis circuit has a non-linear de-emphasis characteristic for relatively attenuating a high .frequency component of the pre-emphasized video signal in a vertical spatial frequency of the picture compared to a low-frequency component of the pre-emphasized video signal, with the degree of attentuation being reduced as the level of the pre-emphasized video signal increases.

Abstract: With the aid of a series of turns (8) wound around the high-tension cable (9) which supplies the distributor, a signal is obtained whose value is proportional to the number of revolutions per minute. This signal is compared with a reference signal in a comparator (16) which controls a logic circuit (3) which in turn causes the deactivation of an electrovalve (6) inserted in the idling channel, this occurring when the number of revolutions of the engine exceeds a certain value and when simultaneously the driver releases the accelerator pedal (4). In all other cases the logic circuit (3) enables activation of the electrovalve (6) and normal operation of the engine. <IMAGE>

Abstract: The method for detecting and monitoring the digital sum variation (DSV), which is determined from the bits of a coded data stream and serves for the detection of transmission errors, involves giving the data bits of binary digit 1 the value +1 and those having the binary digit 0 the value -1 and arranging for the DSV to be limited to a certain predeterminable amount and for an error to be indicated if the DSV exceeds the said predeterminable amount. It is characterised in that the serial data stream is divided into n parallel partial data streams of equal speed, in that in each case one bit of these n partial data streams is buffer-stored in an n-bit memory and in that the pattern of these n bits is detected and, on the basis of a comparison between this bit pattern and the last DSV value, the new DSV is determined from a previously fixed status diagram. Due to the subdivision into n partial data streams, the processing speed for determining the DSV is reduced to 1/n of the transmission speed. <IMAGE>

Abstract: The extruded aluminum spacer frame for insertion between the light-transmitting plates of an insulating-glass pane is formed with one or more pairs of transversely extending aligned openings for admission of a gas into the space within the confines of the frame, for evacuation of a gas from such space, or for regulation of the pressure within the space. If the openings are to be sealed, a tough elastic sealing compound is introduced by way of one opening of each pair so as to form in the internal space of the frame a block which sealingly contacts the inner side of the frame all the way around both openings of the respective pair. A plug is thereupon threaded or driven into one of the openings and close to or even into the other opening in order to urge the mass of sealing compound into sealing contact with the frame around both openings as well as to be maintained in sealing contact with the adjacent material of the compound.

Abstract: @ A gate turn-off thyristor having an array of anode shorts (5) arranged, preferably, in concentric circular formations (11) and a cathode region (4) comprising an array of substantially linear elements (12) parallel to a radius and, divided into a number of sub-arrays each bounded by a sector (AOB) of a circle having a centre (O) co-axial with the anode formations. Preferably the included angle of a cathode array sector (AOB) is no greater than sixty degrees and the cathode strips (12) subtend an angle with respect to a radius which is no more than thirty degrees.

Abstract: A compiler for generating an assembly language listing of instructions for a programmable data processor from a high level programming language has elements for generating from the high level programming language input, an intermediate representation of the programming language input and for generating from the intermediate representation, an assembly language representation of the high level programming language input. The compiler operates generally in accordance with the Glanville-Graham method which enables the compiler to be used with different machines. The resulting retargetable compiler is improved by employing an up/down parsing method in the code generator portion which removes significant restrictions found when LR parsing is employed. The parsing method allows preprocessing of the prefix grammer represent- ing the input intermediate representation for producing, for use by the code generator parsing element, a state table, an extended state table, and a state transition table.

Abstract: A method of initializing a data-recording media (10), particularly tape, by use of the same type of media drive used for data-recording purposes, in which the edge (42) of the recordable field on the media (10) is first located by a test read / write process and the media is then transported in a succession of passes across a transducing head (62), during each of which the head is periodically and selectively energized to write spaced marker bursts (46) and servo-positioning bursts (36, 38), with the transducing head (62) being moved open-loop a distance corresponding to a half-track width between each media transport. During the first such pass, the marker bursts (46) and servo-positioning bursts (36, 38) are located on the basis of tape travel distance, and on successive passes burst location is determined by sensing the previously-recorded marker and servo bursts and timing a predetermined distance therefrom by use of an internal clock. In the case of tape, successive recording passes are made with the tape travelling alternately backwards and forwards.
